7075 Aluminum

Alro stocks 7075 Aluminum, an aluminum alloy with zinc as the primary alloying element. It is one of the strongest commercially available alloys, with a strength comparable to many steels. 7075 aluminum shows good fatigue strength and average machinability, however it is less resistant to corrosion than many other Aluminum alloys. 7075 can be formed by regular methods but requires more care and precision. It is primarily used in applications where cheaper alloys are not suitable, such as aircraft structural members.

Tensile Strength:         83,000 PSI
Yield Strength:            73,000 PSI
Elongation:                 11% Eongation
